Process for filling the bags of a chain of bags or a chain of stacks of bags as well as a device for carrying out the process

Abstract

The invention relates to a process for filling the bags of a chain of bags or a chain of stacks of bags. According to the invention, the chain of bags or the chain of stacks of bags is unwound from a reel, guided over a table, until a bag lies in a suction and filling position on said table. Then the bag is pulled up by means of a suction device, filled, and severed from the supporting web as well as transported away to a depositing table.

1 . Process for filling the bags of a chain of bags or a chain of stacks of bags, characterized by the following steps: 
 unwind the chain ( 8 ) of bags or the chain of stacks of bags from a reel ( 111 ),    guide the chain ( 8 ) of bags or the chain of stacks of bags over a table ( 106 ) until a bag ( 1 ) lies in a suction and filling position on said table,    pull up the bag by means of a suction device ( 100 ),    fill the bag ( 1 ),    sever the filled bag ( 1 ) from the supporting web ( 9 ) of the chain ( 8 ) of bags or the chain of stacks of bags,    transport the bag ( 1 ) away for further processing.    
     
     
         2 . Process, as claimed in  claim 1 , characterized in that, after the filled bags ( 1 ) have been severed, the supporting web ( 9 ) is wound on a reel ( 112 ).  
     
     
         3 . Process, as claimed in  claim 1  or  2 , characterized in that during the opening, filling and severing operation of the bag, the tacking point ( 10 ) between bag ( 1 ) and supporting web ( 9 ) can be fixed in position by means of a holding unit ( 102 ) that can be raised and lowered.  
     
     
         4 . Device for carrying out the process, as claimed in any one of the  claims 1  to  3 , characterized by a table ( 106 ), over which the chain ( 8 ) of bags or the chain of stacks of bags can be guided, and by a suction unit ( 100 ) for opening the bag ( 1 ).  
     
     
         5 . Device, as claimed in  claim 4 , characterized in that the table ( 106 ) exhibits in its end region, lying in the direction of transport of the chain ( 8 ) of bags, a raised putting-down edge, where in the suction and filling position of the bag ( 1 ) the tacking point ( 10 ) of the bag comes to rest.  
     
     
         6 . Device, as claimed in  claim 4  or  5 , characterized in that a holding bracket ( 102 ), which can be raised and lowered, serves as the holding unit.  
     
     
         7 . Device, as claimed in any one of the  claims 4  to  6 , characterized in that at least one photocell ( 104 ) is provided for accurate detection of the position of a bag ( 1 ) of the chain ( 8 ) of bags on the table ( 106 ).
